• Diarrhea. Although there has been interest in using oral gentian for diarrhea, there is insufficient reliable information about the clinical effects of gentian for this purpose.

• Malaria. Although there has been interest in using oral gentian for malaria, there is insufficient reliable information about the clinical effects of gentian for this purpose.
• Obesity. It is unclear if oral gentian is beneficial for obesity. Details: Preliminary clinical research in healthy adults shows that consuming a pudding containing microencapsulated gentian root extract 1.25 g at breakfast modestly reduces caloric intake over 24 hours, but does not affect self-reported feelings of hunger or fullness, when compared with placebo pudding (96534).
• Rhinosinusitis. Oral gentian has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a specific combination product (SinuComp; Sinupret) that contains gentian root 6 mg , elderflower, verbena, cowslip flower, and sorrel improves the symptoms of acute or chronic sinusitis when compared with placebo (374,379). Observational research in adults with acute rhinosinusitis suggests that taking the same combination product orally three times daily, in addition to topical mometasone furoate nasal spray, for 7 days is associated with lower symptom scores when compared with mometasone nasal spray alone (95907).
• Wound healing. Although there has been interest in using topical gentian for wound healing, there is insufficient reliable information about the clinical effects of gentian for this purpose. More evidence is needed to rate gentian for these uses.
